What is Codeium?
Codeium, the AI code completion technology now developed under the Windsurf brand, provides AI-powered inline code completion across 40+ programming languages and all major IDEs including VS Code, JetBrains, Vim, Emacs, and others. The core value proposition is free unlimited code completions for individual developers — a direct alternative to GitHub Copilot's $10/month subscription for the basic completion use case.
Codeium's code completion engine provides suggestions as the developer types, accepting completions with Tab. The suggestions span single line completions through multi-line function completion depending on context. The model understands the current file context and open tabs to provide more relevant suggestions than tools with limited context windows.
The chat interface, similar to GitHub Copilot Chat, allows asking questions about code, generating functions from natural language descriptions, and getting explanations of complex code. This chat feature is included in the free plan for individual developers.
For enterprise teams, the Teams plan at $10/user/month provides privacy controls, custom context from codebase indexing, and team analytics. The Windsurf IDE (now the flagship product) provides a more integrated agentic coding experience beyond the extension.
Codeium's completions are available in over 40 languages including Python, JavaScript, TypeScript, Java, Go, Rust, C++, and all other common languages, with quality generally considered competitive with GitHub Copilot at the base completion task for most languages.
How Codeium works
Codeium runs as llm coding model software built around code and text workflows. Users typically start with a prompt, upload, or connected data source, and the underlying model handles the heavy lifting before returning a result you can refine or export. It's available on vs code, jetbrains, and vim, with API access for teams that want to embed it into their own products.
